/**
 * Changes the 'type' of the 'team_app' route parameter if 'team' is available.
 *
 * The {team_app} parameter has already automatically resolved by
 * EntityResolverManager and it is expected to contain a Team app id (UUID)
 * because this is what entity load can accept. Although, we wanted to generate
 * more user friendly paths for Team apps that does not yet have a _separated_
 * "Team apps" page, similar to "Apps" page for developer apps. Therefore we
 * added the team id (team name) to some regular team app entity routes (ex.:
 * canonical, add/edit/delete-form, etc.) and set the {team_app} parameter's
 * value to team app's name instead of its id (UUID).
